AEMC 3945 Three-Phase Power Quality Analyzer PowerPadT
AEMC’s PowerPad Model 3945 full color
graphical display lets you see and analyze volts, amps and harmonic
content in real time and take pictures to document and analyze clearly.
Its high speed sample rate, at 256 samples per cycle, provides excellent
fidelity in reproducing waveforms and capturing transients that happen as
fast as 62.5µs.
The AEMC 3945 PowerPad’s 4MB of memory is
conveniently partitioned to let you store four different types of data,
synchronized or independent of each other. You can store up to 12 screen
snapshots, up to 50 captured transients that contain four cycles for each
active input, and 4096 alarm events. You can also record trend data for
days, weeks or even months.
Features:
- True RMS single-, two- and three-phase measurements at 256 samples/cycle, plus DC
- Real-time color waveforms
- Easy-to-use on-screen setup
- Automatic current probe recognition and
scaling
- True RMS voltage and current
measurement
- Measures DC volts, amps and power
- Display and capture voltage, current
and power harmonics to 50th order, including
direction, in real time
- Capture transients down to 1/256th of a
cycle
- Phasor diagram display
- Peak voltage and current
- Nominal frequency from 40 to 70Hz
- VA, VAR and W per phase and total
- kVAh, VARh and kWh per phase and total
- Neutral current display for three-phase
- Crest factors for current and voltage
- Transformer K-factor display
- Power Factor, displacement PF display
- Captures up to 50 transients
- Short-term flicker display
- Phase unbalance (current and voltage)
- Harmonic Distortion (total and
individual) from 1st to 50th
- Alarms, surges and sags
- Records date and characteristics of
disturbances
- Immediate printout directly to a
printer
- Screen snapshot function captures
waveforms or other information on the display
- Optically isolated RS-23 communication
port
- Includes DataView®Professional
software for data storage, analysis and report
generation
